Abstract:
Provided is a wiring structure and the like which can completely connect a wiring layer to a body to be wired while keeping insulation between two adjacent wiring layers and realize high density packaging due to a narrowed pitch. In a semiconductor-embedded substrate (1), a conductive pattern (13) is formed on both sides of a core substrate (11) and a semiconductor device (14) is placed in a resin layer (16) stacked over the core substrate. The resin layer has via-holes (19a,19b) so that the conductive pattern and a bump (14p) of the semiconductor device protrude from the resin layer. Inside the via-holes, the bump and conductive pattern are respectively connected to via-hole electrode portions (23a,23b) whose cross-sectional area has been increased toward the bottom of the via-hole. A void is defined between the via-hole electrode portion and upper portion of the inner wall of the via-hole.

The electronic circuit includes: a first layer metal pattern 3 formed on a substrate 1; a polyimide film 2 formed on the first layer metal pattern 3; and a second layer metal pattern formed on a surface of the polyimide film 2. A conductive bump 4 is formed on the surface of the second layer metal pattern 31 by ball-bonding to provide electrical connection with a semiconductor chip 7 bonded to the first layer metal pattern by die-bonding. The conductive bump 4 is electrically connected to an electrode 72 of the semiconductor chip 7 by wire bonding.
Abstract:
As disclosed in Patent Document 1, when a shield case is reduced in thickness so as to promote reduction in height of an electronic component such as a hybrid IC, it is difficult to perform accurate processing of the shied case, for example, by bending because the shield case is made of metal. In addition, the shield case may be markedly deformed due to an external force applied to the shield case during picking up. With the configuration disclosed in Patent Document 2, since a ceramic cap is formed in a box-like shape, if the thickness of the ceramic cap is reduced for reduction in height of the electronic component, waviness may be generated at a top portion 2A, as shown in parts (a) and (b) of Fig. 18. Accordingly, an electronic component 10 of the present invention includes a wiring board 11 having a wiring pattern 14, a surface mount device 12 mounted on an upper surface of the wiring board 11, and a cap 13 for covering the wiring board 11. The cap 13 includes a top portion 13A made of a flat ceramic member, and a leg portion 13B made of a columnar member having a height similar to a height of the surface mount devices 12.

There is disclosed a connection structure and method of a plasma display panel that is adaptive for preventing a short circuit caused by conductive ball mass and improving connection cohesiveness. A connection structure of a plasma display panel according to an embodiment of the present invention includes a first substrate (53) having a plurality of panel-electrodes (54); a second substrate (51) having a plurality of connecting-electrodes (52) arranged to correspond to the panel-electrodes (54); and a connection member (55) located between the first substrate (53) and the second substrate (51) to directly connect the connecting-electrodes (52) with the panel-electrodes (54) upon compression. Accordingly, there is no conductive ball, so the occurrence of short circuit caused by the conductive ball mass of prior art is prevented and, at the same time, the copper electrode (52) penetrates the panel-electrode (54), thereby improving connection cohesiveness.
